A-level Economics, drawn the way you'll draw it in the exam.
Free lessons made by a teacher. Each one takes a diagram and teaches it in drawing order: watch it drawn, try the key steps, build it, then draw it from memory and mark it yourself.
Free. No account needed. Built around the WJEC and Eduqas specification first.
How a lesson works
The same stages in every lesson. If you have already seen the diagram in class, you can jump straight to Try.
- 1GuessPredict the answer before you watch.
- 2WatchClick through it being drawn in exam order, with the reason for each line.
- 3TryClick the key steps yourself. Marked instantly.
- 4BuildPut it together from the pieces.
- 5DrawDraw it from memory, then mark it against the model.
- 6SpotFind the mistake most students make.
- 7ExplainWrite the chain of reasoning and check it.
After the lesson: a retrieval quiz that comes back when it is due, and an exam question you can type or write on paper and mark against the levels yourself.
Lessons
A2 microeconomics, in the order it is taught. 16 of 35 lessons are open.
AS micro: markets and government intervention
Demand and supply6 lessons, in this order
- 01Demand: the curve, movements and shiftsExtensions and contractions along the curve, and the conditions of demand that shift it.
- 02Price elasticity of demandCalculating PED, reading it from the curve, what affects it and why total revenue depends on it.
- 03Income and cross elasticity of demandNormal and inferior goods, substitutes and complements, with the calculations.
- 04Supply and price elasticity of supplyThe supply curve, its shifts and what makes supply elastic.
- 05Price determination and market shiftsEquilibrium, excess demand and supply, and what happens when both curves move.
- 06Consumer and producer surplusThe two triangles, and how they change when the market moves.
Indirect taxes and subsidies4 lessons, in this order
- 07Indirect taxes: specific taxesWhy a specific tax shifts supply up by the tax, why the price rises by less than the tax, and how to show revenue, who pays and the deadweight loss.
- 08Tax incidence and elasticityWho really pays an indirect tax: why the more inelastic side of the market bears more of it, with the extremes and the calculations.
- 09Ad valorem taxesWhy a percentage tax such as VAT pivots supply, with the gap widening as price rises, and how to work VAT out in both directions.
- 10SubsidiesSupply shifts down by the subsidy: who gains, what it costs and whether it is worth it.
Market failure3 lessons, in this order
- 11Negative and positive externalitiesPrivate and social costs and benefits, and the welfare loss triangle.
- 12Public goods and information gapsNon-rivalry, non-excludability and the free-rider problem; asymmetric information.
- 13Government intervention and government failureTaxes, subsidies, regulation and price controls, and why they can make things worse.
Costs, revenue and profit
- 14Short-run costs: MC, AVC and ATCDraw MC as the Nike tick first, then bring AVC and ATC through its lowest point.
- 15Long-run average cost and economies of scaleThe LRAC curve, minimum efficient scale and why firms grow.
- 16Revenue: AR, MR and TRWhy MR falls twice as fast as AR, and why TR peaks where MR is zero.
- 17Profit maximisation at MC = MRNormal profit, abnormal profit and losses on one diagram.
- 18Shutdown points in the short and long runWhy a firm making a loss can still be right to keep producing.
Efficiency and the growth of firms
- 19Productive, allocative, X- and dynamic efficiencyEach type of efficiency marked on the cost curves.
- 20How and why firms growOrganic growth, integration and demergers, as chains of reasoning.
Market structures
Business objectives
Perfect competition2 lessons, in this order
- 22Perfect competition: abnormal profit to the long runWhy profit cannot last when anyone can enter the market, and how to draw the adjustment without the usual mistakes.
- 23Perfect competition: losses to the long run through exitMarket and firm side by side: losses, firms leaving, and the price rising back to the bottom of ATC.
Monopoly2 lessons, in this order
- 24Monopoly: profit maximisation and deadweight lossPrice and output at MC = MR, the profit box, why a monopoly is inefficient, and the case for natural monopoly.
- 25Monopoly: price discriminationFour buyers and some simple numbers show why charging different prices raises profit, the three conditions it needs, and who wins and loses.
Monopolistic competition
Barriers to entry and contestability2 lessons, in this order
- 27Barriers to entry and contestabilityEconomies of scale as a barrier, limit pricing, structural and strategic barriers, and the threat of entry.
- 28Contestability and hit-and-run entryWhy the threat of entry can keep even a monopolist’s price close to average cost, what makes a market contestable, and why perfect contestability is rare.
Oligopoly5 lessons, in this order
- 29Oligopoly: features and concentration ratiosThe features of an oligopoly first, then concentration ratios from real grocery shares and from sales data, and why a few large firms have to watch each other.
- 30Kinked demand (extension)Why prices in an oligopoly can stay put, and the model’s limits. Not named in the WJEC specification: use it for evaluation.
- 31Oligopoly: game theory and Nash equilibriumOne payoff matrix, read the same way every time, and why two firms end up cutting price when both would earn more by not.
- 32Oligopoly: collusion, price leadership and price warsThe cartel drawn as a joint monopoly, the welfare it costs, and why each member is tempted to cheat.
- 33Oligopoly: price and non-price competitionPrice wars, predatory pricing below a rival’s average variable cost, limit pricing, and why oligopolists often compete on everything but price.
Competition policy and privatisation
- 34Competition policyMergers, cartels and regulation, as chains of reasoning.
- 35Privatisation and regulationThe case for and against private ownership of utilities.
New lessons open as they are taught. Market structures come first, then the rest of A2 micro.
For students
Daily retrieval
Questions come back when you are about to forget them: tomorrow, then in three days, a week, a fortnight. What you know stays secure. What you leave fades, and Review shows you where.
For teachers
A five-question starter in one click
Tick the topics your class has covered and get a retrieval starter that mixes last lesson, last week and older topics. Project it, reveal the answers, or print it.
Built on what the evidence says works
Retrieval before re-reading
Every lesson opens with a question, and the ones you get wrong come back later.
Worked examples that fade
The first time, the diagram is drawn for you. By the end of the lesson you draw it alone.
You do the marking
A model answer and the mark scheme levels, not a score from a machine. No streaks, no leaderboards.
